OZONIZING- APPARATUS.

Application filed February 15, 1919.

To all whom it may concern:

Be it known that l, WILLIAM G. Lrnnrr MANN, a citizen of the United States, and resident of Milwaukee, in the county of Milwaukee and State of Wisconsin, have in vented new and useful Improvements in @zonizing Apparatus, of which the following is a description, reference being had to the accompanying drawings, which are a part of this specification.

The invention relates to float controlled means for ozonizing apparatus.

One of the objects of the invention is to provide a float mechanism for automatically controlling the passage of water to be ozonized and the turning on and off of the electric current used in the ozonizing process.

A further object of the invention is to provide a quick acting float for operating the water valve and electric switch by using a float tank of small capacity compared to the tank containing the ozonized water.

A further object of the invention is to provide a simple mechanism for automatically and simultaneously operating the water valve and an electric switch of an ozonizing apparatus.

A further object of the invention is to provide a means for permitting actuation of the float mechanism for difl'erent tank capacities.

A further object of the invention is to prevent unozonized water, dripping from the nozzle, from entering the tank when the electric current is off.

The invention further consists in the several features hereinafter set forth and more particularly defined by claims at the conclusion hereof.

In the drawings:

Figure 1 is a vertical sectional view through the device embodying the inven tion;

Fig. 2 is a section taken on the line 2-2 of Fig. 1

Fig. 3 is a detail sectional view taken on the line 33 of Fig. 2;

Fig. 4 is a section taken on the line 4-4 of Fig. 3;

Fig. 5 is a detail plan view of the float tank; and,

Fig. 6 is an enlarged detail view of the valve shown in Fig. 1.

In the ozonizing apparatus with which the Specification of Letters Patent.

erial No. 277,295.

present invention is used, air from an ozonizer 7 is conducted through a pipe or pipes 8 to a mixing nozzle or nozzles 9 where it is mixed with water led from a supply pipe 10 through pipe fittings 12 and 13 to said nozzle or nozzles and the electric current for ozonizing the air passes through conductors 14. The details of the ozonizer and of the mixing nozzle have not been shown as the invention resides in the control means for the water and ozonizer and to the provision for storage of a certain amount of ozonized water.

Referring to Fig. 3, the passage of water from the pipe 10 is controlled by a valve 15 adapted to register with a seat 16 in the litting 12 and whose stem 17 is slidably mounted in a plug 18. The plug 18 is threaded to seat in the threaded bore of a support 19 which has an exterior threaded end 20 seated in a threaded bore 21 of the fitting 12. The support 19 has a depending forked guide arm 22 and a depending supporting arm 23. The stem 17 has a forked end 24.

The construction of the mixing nozzle and the switch for controlling the passage of electric current through the ozonizing apparatus is more particularly shown and described in my copending application Serial No. 277,294 filed February 15, 1919. Briefly this switch 25 embodies two flexible contacts 26 and 26 mounted in an insulating block 27 and connected to the conductors 14 and moved into contact with each other by means of a push button 28 normally maintained in inoperative position by means of a spring 29 interposed between a shoulder 30 on the button and the block and limited in its outward movement by the flange 31 of a cap 32. A. plate 33 having extensions 34 provided with inwardly extending flanges 35 is secured to the block 27 and is clamped to a plate 36 on the fitting 12 by bringing the flanges 35 in clamping engagement therewith by the tightening up of screws 37 The fittings 12 and 13 are secured to the upper portion of one side of a tank 38. The drip from the nozzles 9 falls into a trough 39 and is conducted away through a drain pipe 40 and in case of any leakage from the valve such water is carried to the trough 39 by a drain trough 41. Thus any unozonized water dripping from the nozzle or leaking from the valve is prevented from entering -51 slidable upon a by a bracket 53 secured to the bottom of the V after which the operation of filling thetank the tank. A pipe '42 conducts the ozonized water from the tank.

A float tank 43 is mounted on legs 44 ad'- justa-bly secured inguides 45 by set screws 46 so that said tank may be set at different with the seat 50 adjacent the opening 47.

The valve 48 is provided with a guide tube vertical pin 52 carr ed tank 43.

Pivotally mounted intermediate its ends" upon the arm 23 by a-pin 54 is the float actuated lever 54 to which the forked end 24 of the water valve is pivotally secured and which has a cup-shaped end 55 adaplt ed,

he other end of this lever is adjustably secured to an upright 56 carried by a float 57 disposed in the tank 43, said upright having to engage the end of the button 28.

a seriesoi' holes 58 into any one of which the pivot bolt 59 for the lever may be inserted so asito provide for ,diflerentsettings I of the float.

The operation of the float mechanism-is as follows: When the tank 38 is empty or is at the water line shown in dotted lines in Fig. 1, the ball valve will be ofl its seat on the tank 43 and the tank 43 will vbe empty and'the float will be in its lower position as shown in full-lines in- Fig, 1, at which time the float lever has moved the valve 15 to open position and has moved the button 28 up againstthe contact 26 andsaid contact against the contact 26 so that as the water flows throughnozzles 9 it is mixed with the ozonized air and theozonized water passes into the tank 38 and continues to flow until it reaches the level shown in full ozonized waterintosaid tank, of means automatically operable iniresponse to a change in water level in the tank for operating the ozonizing apparatus only at-sucli times as to supply ozonizedwater to the tank in largel05 quantities and preventing its operation until lines. As the level of the ozonized water rises in the' tank 38, it carries the ball-valve upwardly until the head 49 engages with the seat 50 to closeofithe bottom of the tank43. When the water reaches its highest.

level in the tank 38, which is determined by the vertical adjustment of the tank 43, it

overflows intothe empty tank43 and fills. said tank, thereby raising the float 57 which in turnswings the lever 54 to the dotted pressure on the switch button 28 is relieved and the switch is opened cutting ofl the electric current to the ozonizing apparatus. As 60 the ozonized water is drawn off from the tank 38 the level of the water in said tank drops but the float remains in its upper shut off position until the water is released from the float tank 43 which occurs when the level of the water in the main tank 38 has dropped to such an extent as to cause the weight of the water in the tank 43 to open the ball valve, which action occurs at aboutthe time the water in the main;tank 38 has reached the level shown;in d'otted lines-in Fig. 1,

with ozonized water is repeated.

While the float might be mounted in the main tank the auxiliary float tank 43 gives tion and arrangement ofparts' shown with.- .80

out departing from thespiritfand scope of the invention, and I thereforedesire it to be understood. that this invention is not limited to any specific form or. arrangement of parts except as such limitations 'are specifled in the claims.

Wh'at-I claim as new and desire to secure by Letters Patent is:

1'. In an ozonizingapparatus, the combi nation, with a supply pipe, of a receiving tank, a mixing nozzle for discharging ozonized water into said tank, a drip trough disposed below the nozzle, a drain pipe for said trough, an outlet pipe leading from the tank,

an electric switch for controlling the flow of current to the ozonizer, and float ,con-

, trolled means for controllinghthe switch and the'p'assage of water throug said nozzle.

2. The combinatlon, wltha storage tank and an ozonizing apparatus d schargnig a large quantity is again .needed, so as toconserve the use of current ilrthe ozonizer.

In testimony whereof I .aflix my signature,

in presence of two witnesses.
